Summary
Children with Developmental Coordination Disorder (DCD) often experience language impairments, with many showing similar language profiles to those with Specific Language Impairment (SLI). This highlights language difficulties as a common co-occurring condition in DCD.
Area of Science:
- Developmental Psychology
- Linguistics
- Pediatric Neurology
Background:
- Developmental Coordination Disorder (DCD) is characterized by cognitive heterogeneity.
- Language skills in children with DCD are not well understood.
- This study investigates language abilities in children with DCD.
Purpose of the Study:
- To compare language abilities in children with DCD to those with Specific Language Impairment (SLI).
- To identify specific language deficits in children with DCD.
- To establish the prevalence of language impairment as a co-occurring condition in DCD.
Main Methods:
- Comparative study involving 11 children with DCD and 11 with SLI.
- Utilized standardized and non-standardized language assessments.
- Included measures of vocabulary, grammar, non-word repetition, recall, retelling, and articulation rate.
Main Results:
- Children with DCD showed impairments in verbal recall and story retelling.
- Nearly half of children with DCD exhibited expressive language measures similar to those with SLI.
- Both DCD and SLI groups had poor non-word repetition; SLI group had slower articulation rates.
Conclusions:
- Language impairment is a frequent co-occurring condition in children with DCD.
- Language profiles in children with DCD and SLI are largely similar, but not identical.
- Further research is needed to fully characterize language profiles in DCD.

01:25Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:29Intellectual Disability
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
